That is because as energy is transferred at least 10% of that energy gets transferred to the next source. That is why.
It took me a bit too figure out and understand but yea, i did it last year now i get it!
Answer:
false
Explanation:
this goes for identical twins: identical twins can have the same level of gene within the genome but they are genetically not identical.
this is due to different stages of cell division that occur during embryo development.
Explanation:
Enzymes are protein structures which speed up the rate of chemial reaction in human systems. They can be found in digestive system, liver etc. They are composed of active sites which are specific to a particular substrate.
Enzymes can only work in certain conditions. These conditions include; pH, temperature etc. Most enzymes in the human body work optimally at around 37°C, which means that at lower or higher temperature they might work sluggishly.
Likewise at certain pH range designed for the part of the body, they'll also work optimally. Example, enzymes in the intestines work best at 7.5 pH while enzymes in the stomach work best at pH 2 (pH of the stomach is much more acidic).
If these conditions in the environment are too high or too low, the enzyme loses its initial shape and hence, alters the shape of the active site.Consequently, the "specific" substrates cannot bind to it because the enzyme has become denatured.
So we know that to transport materials in or out of the cell, we need to have access to both the inside and outside of the cell. This would require that the protein be a transmembrane protein that reaches both the inside and the outside of the cell.
So in this case, let's look at pore proteins. These are proteins that cross a membrane and act as a pore for the materials that need to cross the membrane.
One example of a pore protein is an aquaporin. These proteins aid in the transport of water into or out of a cell.
Therefore, the answer to your question is: A) Pore proteins.
Answer:
I would say a process of energy conversion that releases energy from food in the presence of oxygen, forming new compounds.
Explanation:
Why? Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds
